Abstract: PURPOSE:To suppress error occurrence and to improve the reliability by providing a 1st logic circuit array of logic circuits which input the outputs of specifically-numbered comparators and a 2nd logic circuit array of logic circuits which input their specifically-numbered logic outputs. CONSTITUTION:An (i)th logic circuit in a logic circuit array 5 inputs the outputs of (i)th comparator and the inverted output of (i+2)th comparator. Further, a logic circuit array 6 satisfies zi=yi+y'i+1, where yi is the output of the (i)th logic circuit in the array 5 and zi is the output of the logic circuit in the array 6. Therefore, even-numbered and odd-numbered logic circuits in the array 5 output '1' at the same time, so (z) is the output of the array 6 when outputs (y) are shown in a figure distinctively by even numbers and odd numbers. For example, when an input signal is between 5 and 6, the 4th and 5th logic circuits of the array 5 are '1' at the same time and the output z5 of the array 6 is '1' and converted into a binary number by using an encoder circuit 7 to obtain the A/D-converted value.
